Product details

Module identity and CPU lock

The 6ES7223-1PL20-0XA0 is a SIMATIC S7-200 EM223 digital I/O expansion module, delivering 16 inputs at 24 V DC and 16 relay outputs. It is designed exclusively for S7-22X CPUs.

I/O count and output type

Sixteen 24 V DC sinking inputs and sixteen relay outputs give this module a mixed I/O count that suits applications needing isolated contact outputs alongside DC sensing — valve banks, motor contactor coils, or indicator lamp arrays where the relay common can be wired to a separate supply voltage.

Production status and sourcing

Listed as current production. Sourced to order against RFQ through independent distribution.

Frequently asked questions

How many inputs and outputs does 6ES7223-1PL20-0XA0 have?

16 digital inputs at 24 V DC and 16 relay outputs. The relay outputs are isolated from the backplane and can switch AC or DC loads up to the relay contact rating.

Does 6ES7223-1PL20-0XA0 come with a connector?

The module ships with the required front-pin connectors for field wiring. These are the standard S7-200 expansion module connectors — no separate order needed for the connector itself.

How can I order the 6ES7223-1PL20-0XA0?

This module is sourced to order against RFQ through independent distribution. Availability and pricing are confirmed at quote time.
